Apple may have a temporary exclusive on Intel's fastest workstation Xeons early next year, a purported leak argues tonight. An unnamed source says Apple is readying a Mac Pro based on the Xeon version of Intel's Gulftown six-core architecture and that the Mac builder would have a short exclusive for the processors, launching its own workstations in the winter while everyone else would have to wait until the spring. What configurations would ship aren't known by the MacBidouille tipster.
